Bindiver,

The Woodbine Formation in Texas is composed of inter-bedded conglomerate, sandstone, and shale. In Louisiana, coarse clastics form the lower part of the formation, and the upper part is a marine shale that correlates with marine shales of the Eagle Ford Group that overlies the Woodbine in Texas. The Eagle Ford Trend is a hydrocarbon producing formation of significant importance due to its capability of producing both gas and more oil than other traditional shale plays. It contains a much higher carbonate shale percentage, upwards to 70% in south Texas, and becomes shallower and the shale content increases as it moves to the northwest (hence the trend). The high percentage of carbonate makes it more brittle and “fracable”. The shale play trends across Texas from the Mexican border up into East Texas, roughly 50 miles wide and 400 miles long with an average thickness of 250 feet. It is Cretaceous in age resting between the Austin Chalk and the Buda Lime at a depth of approximately 4,000 to 12,000 feet. It is the source rock for the Austin Chalk and the giant East Texas Field.

So the Woodbine is a hydrocaron prone clastic Formation that holds the carbonate-shales of the Eagle Ford group.

Does that answer your question?
